ROLLER-BEARING,

` Leashes.

To all 'whom' t may concern Be itknown that I, JOHANN H. MODLER, a subject of the Emperor of Germany, and resident of Schweinfurt a. M., Germany, have invented certain'new and useful Improvements in Roller-Bearings, of `which the following-is a specification.

The object of my invention is to provide a roller bearing of the class comprising inner and outer concentric rings having raceways, with rolling members therebetween so arranged as to resist end thrusts and to permit relative angular, movements of the rings with respect to one another,`whereby the rollers will run on `the largest diameter of the raceway of the o uter ring at all times whether the inner ring be parallel with the outer ring or .tilted slightly with respect thereto.

, A.further object ofmyu invention is to provide means to aid the rollers in resisting end thrust between the raceways while permitting the rollers and raceways to have angular movement relative to one another as before stated.

My invention comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

' Reference is to be had to the accompanying drawings forming part hereof, wherein, Figure l is a central section of a roller bearing embodying. my invention; Fig. 2 1s a similar view, showing the 1nner ring and its rollers tilted with respec to the outer ring;

Fig. 3 is a view similar to Fig. l, showing the bearing provided with end-thrust resist I Fig. 5' is adetail section through Fig. 3,

having the inner raceway la, and the-inner concentric rings, and the rollers 3 fitted be'-v tween said raceways are longitudinally shaped to correspond to the transverse curvature of the raceway. la. The raceway 2a is also curved to correspond to the peripheral lengthwise curvature ofthe rollers 3, so that said rollers will roll freely between said raceways in all positions that said rings l and 2 may assume with relation to one another, as illustrated in Figs. 2 and 4. The raceway 2a is cut somewhat deeply inthe ring 2, providing side shoulders 2b at the ends of the rollers 3, between which shoulders saidl rollers fit somewhat snugly and yet with sufiicientfreedom for proper rotation, whereby side thrust upon ring 2 will. be transmitted directly to`rollers 3, and the latter are maintained in proper positions and have endwise or angular movement equally with ring 2. At Il are retaining rings at the ends of rollers 3, and at 5 are separators between rollers 3, suitably shaped on the faces to coact with l said rollers, which separators are shown provided with studs or projections 5a that pass through corresponding holes in the retaining rings 4, and may be hieaded over to maintain rings l and separators 5 in proper relation.

W ith the construction described, rollers 3 will always roll on the 'largest diameter of the raceway li* of the outer ring, whether the rings 1 and 2 be parallel, as in Figs. l and 3,

or whether the rings tilt or incline angularly rings, to resist'end thrust upon one or both rings 1, 2, in any position that the latter assume with relation to one another.

To afford end thrust resistance additional to that afforded by the rollers 3 between the race'ways, while at the same time permitting the inner and outer rings to assume an angular relation. with respect to one another, I provide end-thrust resisting-members 6, located between the rings 1, 2 and at the` ends of rollers 3, which members are shown in ring-like form having their outer surfaces 6 curved transversely to correspond to the transverse curvature of raceway 1a, the inner circumference 6b of the members 6 substantially corresponding to the annular outer surfaces 2c of the inner ring 2 at the sides of shoulders 2l. With this construction the ring Q'and member 6 .with the rollers may assume angular relation with respect to ring 1,' in manner before described, as illustrated in Fig. 4, since members 6 will have free swinging motion within raceway 1El similar to such movement of rollers 3, but

' against raceway 1a and serve to-resist such I claim is end thrust, either when rings 1, 2, are parallel or at an angle with respect to one another. s

The bearing may be assembled by fitting rollers 3 upon ring 2, with the retainer 4 in position, and then suitably tilting inner ring 2, and .swinging 'the same into ring l, in accordance with Figs. 1 and 2, and when the bea-ring illustrated in Figs. 3 and 4 is to be assembled, the end thrust members 6 may be applied upon ring 2 and then the parts may be assembled in the manner described with respect to Figs. 1 and 2.

An oscillatory bearing havingv inner and outer rings provided -with opposed raeeways, the raceway of the outer ring spondingly curved but in a direction reverse to said curvature of the raceway of the outer ring, and rollers fitted between said raceways corresponding to the curvature of said raceways and having parallel side faces, the inner ringA having shoulders extending beyond its raceway and Iembracing the parallel side faces of said rollers.
